The FBI is investigating a Hartford, Connecticut, plane crash after one of the survivors said a Jordanian man purposefully downed the aircraft.

Flight student Feras Freitekh, 28, died Tuesday when the twin-engine plane he was flying crashed just outside the headquarters of Pratt & Whitney. His instructor survived the crash and told investigators it was no accident the Piper PA-34 Seneca exploded near the military and commercial jet engine maker’s complex.

The National Transportation Safety Board released a statement Tuesday confirming the FBI’s involvement and indicators that “the crash is the result of an intentional act,” CBS News reported.
